Embedded sensors for indoor positioning

Indoor location-based applications have a broad appeal for development in navigation, robotics, gaming, asset tracking, networking, and more. GPS technologies have been successfully leveraged for outdoor navigation, but often lose effectiveness indoors due to a more constrained environment, possible loss of signal, lack of elevation information and need for better accuracy. This paper presents our experimental results to create an indoor positioning system using a current model Smartphone: the Apple iPhone 4 and the embedded sensors.
